DOOR FITTINGS Filed Sept. 9, 1963 4 Sheets-Sheet 4 20 a Fly/12 J0 United States Patent() 3,157,418 DOGR FITTINGS Robert Duncan, 1/13 VJ. Campbell St., Glasgow C. 2, Scotland Filed Sept. 9, 1963, Ser. Ne. 397,540 6 Clmrns. (Cl. 292 229) This invention has reference to door fittings.

A door stop is provided to limit the opening movement of the door and thereby protect the door and door ttings from damage. Usually a door stop is in the form of a rubber or like cylinder which is secured to the floor and which projects upwardly therefrom to contact with the foot of the door when the latter is opened. The most effective position for the stop is such that it contacts with the door near to the opening edge or locking stile of the door. Generally its position is such that it is not less than one third of the width of the door from the hinge side thereof. When the door is opened it abuts against the stop which acts as a fulcrurn. The nearer the stop to the hinge side of the door the greater is the danger of damage to the door and its fittings. n the other hand the further the stop is from the hinge side of the door the greater is the danger of people tripping over it.

Where door holders are provided to retain the door in its open position they are in some cases secured to the floor to engage with the foot of the door.

It will be apparent that door holders secured to the fioor and projecting upwardly therefrom constitute a danger in that people may trip on such projections.

The present invention has therefore for its object to provide an improved door stop, or door holder, or a combined door stop and door holder which will not constitute a danger to people passing through the doorway.

According to the present invention a door is provided with fittings comprising a keeper or stop sunk into the floor at a position remote from the hinge side of the door, a finger or other member carried by the foot 'f of the door and which is lowered to co-operate with the keeper or stop when the door is opened and a fixture in the form of a cam or ramp located at the hinge side of the door, the carn or ramp controlling the movement of the finger or other member.

The invention further consists in a door having fittings comprising a keeper sunk into the floor, a finger pivoted to the foot of the door at or near the lock side thereof, a rod, blade or the like operatively connected to said finger and extending along the foot of the door to near the hinge side 'thereof and a cam or ramp positioned near the hinge side and which, when the door is being opened, actuates the link or blade to cause the finger to engage the keeper.

The link or blade may be fuicrumed to the door near the hinge side thereof and its shorter arm connected to a runner or roller which rides on Vthe ramp when the door is being opened, the rod, blade or the like being thereby rocked about its fulcrum to cause the finger to engage the keeper. Or the inner end of the link or blade may be arranged to engage a fixed cam when the door is being opened, the cam imparting a thrust which is transmitted to the finger which then drops to engage the keeper.

Preferably the keeper is in the form of a trough to receive the finger, the trough having a bridge towards one end thereof. When the finger is lowered it enters one end of the trough and sweeps any rubbish collected therein along the trough until it contacts with the bridge, the rubbish being discharged at the other side of the bridge. i

A preferred embodiment of the invention will now be A, 3,157,418 Patented Nov. 17 1964 ICC described with reference to the accompanying drawings wherein:

FIGURES 8 and 9 are views corresponding to FIG- URES 1 and 4 respectively but showing an alternative construction of fitting in Vaccordance with the invention;

FIGURE 10 is a section on the line 1.0 10 of FIG- URE 9; and y FIGURES 11 and 12 are further Views corresponding to FIGURES 1 and 4 respectively but showing a further alternative construction of fittings in accordance with the invention.

In the drawings like reference numerals denote the same or corresponding parts.

The invention will first be described with reference to FIGURES 1 to 7 wherein 10 denotes a plate glass door the foot of which is inserted in the upper channel 11 of an H channel bottom rail 12. The door is supported by means of a lower vertical pivot pin 13, and is also supported by an upper pivot pin, not shown. In the lower channel 14a is housed a rod 14 secured to a sleeve 15 rotatable on a pin 16 inserted through the bottom rail near the hinge side of the door. The eX- tremity of this rod near the hinge side carries a roller 17. A wire spring 18 encircles said sleeve one end of the wire bearing on the under side of the base of the bottom rail and the other end thereof engages the rod and tends to turn it in a clockwise direction as shown in FIGURE 3. The other end of the rod 14 is connected to a lug 19 projecting upwardly from the upper side of a finger 20 rigidly secured to a pivot pin 21 extending between the two anges forming the lower channel of the rail.

Secured to the floor at the hinge side of the door is a ramp 22 up which the roller 17 runs when the door approaches its fully open position, Which may be when it has been turned about Sunk into the oor is a keeper in the form of a flanged trough 23 into which the tinger projects when the roller rides on the ramp. This trough is provided with a bridge 24 near one end thereof. s r

When the door is swung to its open position, i.e. from the closed position shown in FIGURE 1 to its open position, the roller 17, just before the door reaches its open position, rides on the ramp and is thereby raised against the action of its spring 13. The rod is thereby rocked about its fulcrum, i.e. the pin 16, and turns the finger 20 so that the latter projects into the trough 23. The finger travels along the trough until it abuts against one side of the bridge 24, further movement of the door being thereby arrested, See FIGURE 6.

Should any rubbish accumulate in the stopV it is swept by the finger below the bridge to emerge from the trough at the other side of the bridge.

When the movement of the door is reversed the roller 17 runs down the ramp 22 and the rod 14 is rocked to pable of rotating through 140 or more. 1

I free to close.

The position of the door when the finger abuts against the bridge of the stop is determined by the position of the ramp and the stop.

As the ramp is Vpositioned'near the hingeV edgey or stile'of the door and the'V keeper or stop is sunk in the floor to be flush therewith there is no projection over which those entering and leaving the doorV can trip.

K-f desired the door maybe provided with two ramps and two stops or keepers, one of thev ramps and a stop or keeper coming into operation when the door is opened in: one direction Vand the otherV ramp and stop or keeper coming into operation when the door is opened in the other'direction. Y Y

If desired the pivot pin 21 to'whichY the finger is rigidly secured' maybe provided with saw'cuts or a hexagonal or square or recessed head or otherwise formed so that the pin can be rotated and therefore the finger raised and lowered Vmanually by meansl of a suitable tool,.the end of the' finger having a claw which can engage both sides of said bridge 241, see FIGURE `7. When such finger is raised and thereafter lowered to so engage the bridge the door is retained in its openposition until the finger is againmanallyraised.

The invention is likewise applicable to banks of doors positioned between two doorposts, each door being ca- In the embodiment of the invention shown inY FIG- URES'S to'IO near the bottom pivot of the door is a fixed cam 22 and arranged to co-operate therewith isa roller 17 mounted on the end of the rod 14. The other end of the rodV is connected to the lug 19 rigidly secured to the finger 20 which is pivoted on a pivot pin 21 extending Ytransversely of the bottom., rail 12. The rod is encircled bya' helical compression spring 25 one end of tion against the action of the spring by the roller 17 'co-operating'withthe cam 22. VVThis causes the finger to turn about'ri'tspivot' andL engage the bridge of therkeeper or stop sunk into the fioor. The finger may be raised from' its keeper by means of a key or other tool. When theV door commences toclose the' spring4 movesA the Vrod I4 to raise the finger clear of the keeper or stop. When the finger engages the bridge it may be raised and then dropped toengage the other side of Vthe bridge to retain the door open. Y

In the embodiment of the invention shown in FIG- `URES -114 andf 12 the rod 14 is mounted in bearings 14a so thatv itV can partake of Varotary movement about its own axis.

When the door is about fully opened the cam 22 cooperates with the adjacent cranked end of Vthe rodY I4 thereby turning the rod about its own axis. The other cranked end engages the linger 20 to turn it about its pivot against the action of the spring 29, thefinger then engaging the keeper or'stop. When the door thereafter Vcommences to close therfinger is raised clear of the l keeper or stop by the spring 29, the rod being rotated about its own axis to its initial position.

The housing may be provided with two cams and two sockets provided Vto receive the linger, the cams and sockets being suchV thatthedoor is held in its open position when opened inwards or outwards.
